Large coastal roofs on strata and retail take the full salt load — the right system lasts. Serving Craigie 6025 and the surrounding coastal areas.
Fully licensed & accredited — Builders Registration BC105819 · Painters Registration PC102072 · Patent ID AU-A-2020100623
Commercial roofing covers the larger, higher-stakes roofs — factories, warehouses, strata, retail and offices — where a leak means downtime, stock damage or a strata levy, not just a stained ceiling. We re-roof metal deck, install and repair membrane, and run scheduled maintenance, all planned around an operating business, and backed by a proper roof inspection and report. As WA-registered builders we can also handle structural work and certify it. Free inspection, written quote, 10-year workmanship warranty. Serving Craigie.
Commercial roofing in Craigie: the short version
A commercial roof is a business asset, and a failure on one is measured in downtime and damaged stock as much as repair cost. The work is the same disciplines as residential — done at scale, to spec, and scheduled so it doesn’t stop the business underneath it. We do the same through nearby Kallaroo; more on our commercial roofing service page.
Why Craigie roofs behave the way they do
Craigie exists because of a single administrative act: in 1969 the State Government rezoned a large area of coastal land for development, creating four “Whitfords” suburbs of which Craigie is one. Being released and built as part of one coordinated decision gave it a tight build window. Consistent 1970s housing, which means the same era-specific problems tend to recur right across the suburb, useful to know before an inspection begins. Chief among those problems is the roof. Craigie's 1970s tile roofs sit under three kilometres from the ocean and the suburb is rated high for delignification, putting it squarely in core territory for the defect. Timbers under an unrenewed roof are the first thing to examine and salt of that duration also works steadily on gutters, flashings and fixings of the same age. The suburb's schooling history says something about its people. That is the pattern. Craigie Senior High opened in 1976 and closed in 2003 as enrolments fell, the mark of a suburb whose original families grew up and stayed. In practice that means homes held by the same owners for decades, with original fittings, dated services and maintenance deferred, but often sound underlying structure. As that generation moves on, subdivision and rebuilds are appearing among the original houses, so establishing whether a property is 1970s stock or recent infill is the necessary first step.What that means for commercial roofing in Craigie
Coastal commercial roofs around Craigie — strata blocks, retail and offices near the water — take the full salt load across large metal areas, so corrosion of sheeting, fixings and flashings is the main enemy. Specifying the right grade from the start is what makes the difference between a 10-year and a 25-year roof.
We re-sheet and re-flash in coastal grades, and set up maintenance so small corrosion issues are caught before they become a leak over stock or common property.
It’s the same commercial work we carry out through Hillarys and Padbury, and a planned approach beats an emergency call-out over damaged stock.
Craigie commercial roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Water over stock or a tenancy | Box gutter or membrane failure | Assess and renew the detail |
| Rust across large sheeted areas | Sheeting/fixings corroded | Re-sheet in correct grade |
| Ponding on a flat section | Fall or membrane failing | Re-waterproof, correct fall |
| Leaks around skylights/penetrations | Flashing or surround failed | Re-flash or replace |
Guide only. Every building differs, which is why we inspect and scope before quoting.

Roof Replacement in Craigie
Learn moreWhen a Craigie roof reaches the end of its life — porous tiles, rusted-through valleys, or a roof that’s been patched one too many times — a full re-roof is often the honest answer. We strip the old covering, check and repair the timber and battens underneath, and install a new tile or Colorbond roof with fresh sarking, valleys and flashings throughout.
A tile-to-Colorbond conversion is popular here for its lighter weight, clean lines and colour range, and because the lighter roof changes the wind uplift we reassess the tie-down as part of every conversion. We’ll also be straight about whether you’ve genuinely reached replacement or whether a restoration, as we do through nearby Kallaroo, would renew the roof for a fraction of the cost. Every re-roof is engineered and tied down to Australian Standards and backed by our 10-year workmanship warranty, and we handle the guttering, flashings and tie-down as one job so nothing is left for you to chase afterwards.

Roof Repairs in Craigie
Learn moreMost Craigie roof problems come down to a handful of failures: cracked or slipped tiles, perished ridge pointing, rusted valley irons and tired flashings. We trace the leak to its actual source — which is rarely under the ceiling stain — and fix the cause, whether that’s replacing matching tiles, re-bedding and re-pointing the ridge in a flexible compound, or renewing a corroded valley.
We’ll always tell you honestly when a roof is genuinely repairable versus when the repairs are mounting up and a restoration would serve you better, as it often does through nearby Hillarys. Prompt repair matters: a single cracked tile left through a wet winter becomes soaked insulation, stained ceilings and, eventually, damaged roof timber. Every repair is backed by our workmanship warranty, and because we photograph what we find and talk you through it, you’ll understand exactly what was wrong and what we did about it rather than being handed a bill and a shrug.

03Roof Restoration in Craigie

Roof Restoration in Craigie
Learn moreA roof restoration renews a tired but sound Craigie roof for a fraction of replacement: we treat the moss and lichen, high-pressure clean, replace broken tiles, re-bed and re-point the ridge caps in a flexible compound, then seal and coat with a Dulux AcraTex membrane as accredited applicators.
It’s the right call when the tiles have decades left but the surface and pointing are gone — the same judgement we bring to nearby Padbury. We’ll tell you honestly whether a restoration suits your roof or whether repairs or a re-roof make more sense, and the finished job carries both a manufacturer coating warranty and our 10-year workmanship warranty. Most Craigie homes take two to three days depending on the repairs needed before coating. As accredited applicators we prepare to the manufacturer’s specification, so the membrane actually holds — a coating only lasts if the surface beneath it was treated, cleaned and repaired properly first, which is exactly where a cheap spray-over fails within a couple of summers.

04Roof Inspection in Craigie

Roof Inspection in Craigie
Learn moreA roof inspection is the cheapest way to know exactly what your Craigie roof needs before you commit to anything — or before you buy. We get onto the roof and into the roof space, physically checking the tiles, pointing, valleys, flashings, gutters and the structural timber, then hand back a clear written report with photographs.
On older homes we test the timber for rot, termite damage and delignification; on newer ones we look for the builder-grade detailing faults that leak early. It’s the same thorough check we run through nearby Connolly, and it’s what tells you whether a roof needs a minor repair, a restoration or something structural. If you’re buying a home, an inspection of the one part most people skip — the roof space — is money very well spent, and the written report gives you something concrete to put in front of an agent, a buyer or your insurer rather than a verbal all-clear.

05Roof Carpentry in Craigie

Roof Carpentry in Craigie
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Craigie homes we repair and rebuild that framing to standard: sistering weakened members, replacing rotted or termite-damaged timber, and reinstating trusses that have been cut for a skylight, duct or downlight.
We also test for delignification, the chemical breakdown that leaves roof timber looking sound but unable to hold a fixing — the same treatment we carry out through nearby Edgewater where the timber is worth saving rather than replacing. As registered builders we can certify structural carpentry, which a general handyman can’t, and we assess the whole load path while we’re in the roof space so a repair addresses the cause, not just the symptom. Where a member is load-bearing we prop it safely with acrow props and work to a structural engineer’s design before anything is cut — it’s the natural companion to our tie-down and structural-defect work.

06Structural Defect Repairs in Craigie

Structural Defect Repairs in Craigie
Learn moreWhen a building or pest inspection flags a roof-framing defect — a sagging rafter, a cut truss, inadequate bracing, rot or termite damage — the REIWA contract needs it rectified before settlement, and in Western Australia that rectification must be certified by a registered builder. Powerdrive holds Builders Registration BC105819, so we can both rectify the fault and certify it for your Craigie sale.
We assess the defect, bring in a structural engineer where a load-bearing member is involved, and put it right — propping, sistering, reinstating cut members and adding the connections the frame needs. It’s the same certified rectification we handle through nearby Kallaroo. An unregistered handyman can patch the timber but can’t certify it, which is exactly what stalls a settlement. An engineering assessment typically runs $800 to $2,000 and gives everyone a defined scope, and we hand back a documented record you can pass straight to the buyer — so it’s done once, properly.

Signs a Craigie commercial roof needs work
- Water appearing over stock, machinery or a tenancy after rain
- Widespread rust, ponding or debris in box gutters visible from access
- Recurring leaks around skylights, penetrations or parapet flashings
If that’s your Craigie premises — or a building you manage in nearby Connolly — a planned assessment beats downtime. It’s worth knowing the realistic life of a roof and reading the signs a roof needs attention.
Local conditions in Craigie
One of four suburbs created by a single 1969 State Government rezoning of coastal land, meaning Craigie was released. Built as part of one coordinated planning decision, giving it a tight build window and consistent 1970s stock. The same era-specific issues recur suburb-wide.
1970s tile roofs less than 3km from the ocean, rated HIGH, this is core delignification country. Roof timbers on unrenewed roofs are the first priority; salt also works on gutters, flashings and fixings of this age.
The high school opened in 1976 and closed in 2003 as enrolments fell, an ageing suburb with long-tenure owners, so expect original fittings, dated services and deferred maintenance alongside well-kept structure.
We cover the whole of the City of Joondalup. Around Craigie that takes in Wanneroo and Padbury. Short drives keep roof replacement affordable on smaller jobs and most of ours are smaller jobs.
Specification, access and compliance
On a commercial roof the grade of sheeting, the box-gutter sizing and the membrane system are what determine whether it lasts, so we specify to the exposure and the use, using Lysaght and manufacturer systems, with proper height access and safe-work method on site.
As WA-registered builders (BC105819) we can also certify structural work on the roof, which a sheeting-only contractor can’t — and comparing scopes not just prices matters even more on a large asset where a cheap job fails expensively.
A little about Craigie
Craigie Senior High School opened 1976 and Closed IN 2003 following a decline in student enrolments; students moved to Padbury or Belridge (Padbury itself closed in 2011) 2.7km from the coast; delignification risk High; 20.6km NNW of the CBD Name chosen 1970, honouring an early councillor of the City of Wanneroo; Craigie is ONE OF THE Four 'Whitfords' Suburbs that resulted from the State Government Rezoning A Large Area OF Coastal Land FOR Development IN 1969; established 1970s; ~4.6km², ~6,456 pop None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Craigie.
What the work involves
- Assess the asset. A proper inspection of sheeting, box gutters, membrane, flashings and penetrations, with a written report and scope — no guesswork on a large roof.
- Metal deck & membrane. Re-sheeting in the correct grade, membrane and waterproofing on flat sections, box-gutter upgrades and skylight replacement.
- Structural where needed. As registered builders we can address and certify structural issues — purlins, bracing and framing — that a sheeting contractor can’t.
- Planned around the business. Staged works, out-of-hours where needed, proper height access and safety, and scheduled maintenance so the roof is managed, not just repaired when it fails.
Common questions about commercial roofing in Craigie
Can you work around our operating business?
Yes — that’s standard on commercial jobs. We stage the work, do noisy or disruptive stages out of hours where needed, and keep the site safe and access controlled so trade continues underneath.
Do you handle box gutters and membrane, not just sheeting?
Yes — box gutters, membrane and waterproofing on flat sections, skylights, penetrations and flashings are the details that actually cause most commercial leaks, and we repair or renew all of them.
Our coastal building keeps rusting — what’s the fix?
Near Craigie the salt load is high, so it comes down to grade — we re-sheet and re-flash in coastal grades and maintain it, rather than replacing cheap sheeting every few years.
Can you certify structural work on a commercial roof?
Yes — as WA-registered builders we can address and certify structural issues like purlins, bracing and framing, which a sheeting-only contractor can’t sign off.
Do you offer scheduled maintenance?
Yes — on a large roof, scheduled maintenance catches small issues before they become leaks over stock. It’s far cheaper than an emergency call-out and the damage that comes with it.
Do you do commercial roofing throughout Craigie and nearby?
Yes — across Craigie and neighbouring areas including Kallaroo and Hillarys. Ring 0421 768 842 and tell us about the building. We’ll inspect and scope it properly before quoting.
